Abstract:
We record a case of systemic mastocytosis in a 70 year old male whose clinical picture started with abdominal symptomatology (pain and diarrhea) and syncopal episodes, who was found to have hepatosplenomegaly and skin, bone and bone-marrow involvement. Papulo-erythematous lesions appeared over the scar tissue of a previous colyscectomy. Scratching of these lesions produced urtication. Histologically an infiltration of mastocytes was found, being compatible with the diagnosis of systemic mastocytosis with Köebner's phenomenon. We review the most remarkable characteristics of systemic mastocytosis.

Disorders of Leukocytes
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune system...
